A time-dependent model for plasma spectroscopy of K-shell emitters

The purpose of this report is to provide information on the suite of computer codes called FLY that allow one to understand the plasma spectroscopy of K-shell emitters. The code suite provides the basics for designing and/or analysing experiments where single-electron spectra are to be observed. The models incorporated are capable of generating information on lithium-like, helium-like and hydrogenic species from Z = 2 to 26, i.e., from helium to iron. This restriction in atomic number is dictated by the availability of data and interest in these elements. The code suite runs on any UNIX workstation or PC, thus allowing access to fairly sophisticated models while providing graphical output of populations, intensities, optical depths, as well as detailed spectra including Stark broadened transitions.
